Question

Name the following:

A compound added to lower the fusion temperature of electrolyte bath in the extraction of aluminum

Answer 1

1. The ore of Aluminum is Bauxite($\mathit{A}{\mathit{l}}_{\mathbf{2}}{\mathit{O}}_{\mathbf{3}}$).
2. During the extraction process of Aluminum, the compound Cryolite is added for reducing the melting point of Alumina.
3. The formula of Cryolite is $\mathit{N}{\mathit{a}}_{\mathbf{3}}\mathit{A}\mathit{l}{\mathit{F}}_{\mathbf{6}}$.
4. So Cryolite is the compound added to lower the fusion temperature of the electrolyte bath in the extraction of aluminum
